Now that season 2 is over I stand by my prediction that The Mandalorian will be very similar to Rebels in its overall structure. I.e. we’ve now had the simple and mostly self-contained first season, and a cameo-filled second season with more characters and ties to the larger SW galaxy while still sticking to the main arc. Both shows also had a pretty big dramatic finale that shook things up a fair bit and planted the seeds for future plot-points. My guess is that season 3 will be much more story-focused while still being somewhat episodic and that season 4 (the final season) will mostly be one long story arc. Now that Din has the darksaber my guess is that the show will culminate in the retaking of Mandalore and that this will cross over with Ahsoka (who has a history with Mandalore and Bo-Katan) as probably as Rangers of the New Republic as well.
